97a11c107e CMake: allow to build both shared and static at once 
This allows for more fine-grained control. Possible combinations:
  * static off, shared on
  * static on, shared off
  * static on, shared on

The static library is always called "libpolarssl.a" and is only used
for linking of tests and internal programs if the shared lib is
not being built.

Default is: only build static lib.

From kernel objects at msdn:
    Kernel object handles are process specific. That is, a process must either create the object or open an existing object to obtain a kernel object handle. The per-process limit on kernel handles is 2^24.

Windows Internals by Russinovich and Solomon as well says that the high bits are zero.

14a222cef2 Moved PKCS#12 PBE functions to cipher / md layer where possible 
The 3-key and 2-key Triple DES PBE functions have been replaced with a
single pkcs12_pbe() function that handles both situations (and more).

In addition this allows for some PASSWORD_MISMATCH checking

b495d3a2c7 x509parse_crt() and x509parse_crt_der() return X509 password related codes 
POLARSSL_ERR_X509_PASSWORD_MISMATCH is returned instead of
POLARSSL_ERR_PEM_PASSWORD_MISMATCH and
POLARSSL_ERR_X509_PASSWORD_REQUIRED instead of
POLARSSL_ERR_PEM_PASSWORD_REQUIRED

1fd4321ba2 PKCS#5 v2 PBES2 support and use in PKCS#8 encrypted certificates 
The error code POLARSSL_ERR_X509_PASSWORD_MISMATCH is now properly
returned in case of an encryption failure in the padding. The
POLARSSL_ERR_X509_PASSWORD_REQUIRED error code is only returned for PEM
formatted private keys as for DER formatted ones it is impossible to
distinguish if a DER blob is PKCS#8 encrypted or not.

pbeWithSHAAnd3-KeyTripleDES-CBC and pbeWithSHAAnd2-KeyTripleDES-CBC)

65a1909dc6 Internally split up x509parse_key()

DER parser functions for the PKCS#1 (x509parse_key_pkcs1_der()) and
unencrypted PKCS#8 (x509parse_key_pkcs8_unencrypted_der()) private
key formats.

Paul Bakker
6417186365 x509parse_crt() now better handles PEM error situations 
Because of new pem_read_buffer() handling of when it writes use_len,
x509parse_crt() is able to better handle situations where a PEM blob
results in an error but the other blobs can still be parsed.
 2013-06-06 15:01:18 +02:00
Paul Bakker
9255e8300e pem_read_buffer() already update use_len after header and footer are read 
After header and footer are read, pem_read_buffer() is able to determine
the length of input data used. This allows calling functions to skip
this PEM bit if an error occurs during its parsing.

a62729888b Ability to specify allowed ciphersuites based on the protocol version. 
The ciphersuites parameter in the ssl_session structure changed from
'int *' to 'int **' and is now malloced in ssl_init() and freed in
ssl_free().

The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.
